Filed: 1966-09-05
Abstract: 1,157,001. Pyridine and substituted pyridine. IMPERIAL CHEMICAL INDUSTRIES Ltd. 18 Sept., 1967 [5 Sept., 1966], No. 39581/66. Heading C2C. The invention relates to a process for the manufacture of pyridine or substituted pyridine which comprises interacting a starting material containing a partly or fully reduced pyridine ring, e.g. piperidine or tetrahydropyridine with molecular oxygen in the liquid phase in the presence of ions of a metal of variable valency, for example, iron, cobalt, nickel or chromium, but the use of cupric ions is especially preferred, which ions may be derived from inorganic salts, for example, cupric nitrate, cupric or ferric halides or ferric ammonium sulphate, or from organic salts; in particular salts of carboxylic acids may be used, for example cupric acetate. Whether the metal ions are present or not, it is preferred to carry out the reaction in the presence of ammonium ions preferably introduced in the form of an ammonium salt; such as aliphatic carboxylic acids (for example ammonium acetate) and the salts of mineral acids (for example ammonium sulphate, ammonium nitrate and ammonium halides). Alternatively, gaseous ammonia or a solution of ammonia may be introduced into the reaction mixture. Amides hydrolysable to form ammonium ions, for example formamide or urea, may also be employed. The examples show the production of pyridine from 1,2,3,6-tetrahydropyridine and piperidine.

Filed: 1973-08-21
Abstract: 1416940 Magnetic position indicators SIEMENS A G 21 Aug 1973 [21 Aug 1972] 39666/73 Addition to 1329627 Heading G1N Apparatus for use in such devices as position indicators, limit value signallers or null indicators of the type which includes two magnetic field sensors and a magnetic flux generator movable relative thereto as shown in Specification 1329627 has the magneto-resistors connected in a differential circuit. Position indicator, Fig. 1 Two magnetic field sensing devices 2, 4 including permanent magnets 10, 11 flux return paths 13, 15, 17 and 12, 14, 16 and magneto resistive members 18, 19 are separated by a gap 5 filled with diamagnetic material such as air. A magnetic flux generator in the form of a permanent bar magnet 6 is mounted on the apparatus whose position is to be indicated e.g. a rotatably movable member so that it moves past the devices 2, 4 in the direction of arrow 8. The magneto-resistive members are connected in adjacent arms of a D.C. energized resistance bridge. As the bar magnet 6 moves either to the left or right of the position shown the magnetic flux in one of the magnetoresistive members varies whilst the net flux in the other member remains more or less constant. Thus the output voltage across a bridge diagonal varies positively and negatively linearly with the displacement of the magnet 6 over a limited range, Fig. 3 (not shown) and is insensitive to variation in the distance "b" between the magnet and field sensing devices. Limit value signaller, Fig. 6 The arrangement of Fig. 1 is modified by the magneto-resistive members being remote from each other. When magnet 6 is displaced from the central position there is little variation in the resultant magnetic flux passing through the magneto-resistive members and the bridge output remains zero. Beyond a certain range of movement (dead zone) a positive output maximum is produced (movement to the left) or a negative output minimum (movement to the right). Another arrangement having a "dead zone" comprises two sensing devices as shown in Fig. 1 but the magnet 6 is in the form of a U-shaped magnet whose respective pole limbs extend towards the devices respectively.

Title: Character recognition device
IPC: G06V10/75
Filed: 1967-09-01
Abstract: 1,132,548. Character recognition. NATIONAL CASH REGISTER CO. 1 Sept., 1967 [23 Dec., 1966], No. 40129/67. Heading G4R. In a character recognition device, signals produced from the scanning of different portions of a character are applied to different operational amplifiers to produce analogue output signals from which analogue difference signals are obtained, the analogue output and difference signals being digitized and logically combined to specify the character. The video signal obtained from a raster scan of a character is gated to integrators (comprising operational amplifiers with capacitive feedback) under control of a clock-driven counter arrangement so that each integrator receives the signals in a respective area of the scan field having the shape of 1, 2 or 3 rectangles. One of the integrators integrates over the whole scan field to provide a threshold analogue output with which the other integrator analogue outputs are compared at Schmitt triggers to digitize them each to a binary level. The outputs of some of the integrators including the whole-scan integrator are added and subtracted in groups using operational amplifiers having resistive feedback to produce analogue outputs which are compared with positive and negative versions of the threshold from the whole-scan integrator at Schmitt triggers to digitize each to two binary levels, viz. above +V or not, and below -V or not where +V is the positive threshold and -V the negative. All the digital signals mentioned are ANDed and ORed in true and inverse form to identify the character.

Title: Shaft rotation detector
Inventor: BOWDEN DAVID NEIL
IPC: G01P13/04
Filed: 1966-09-12
Abstract: 1,138,555. Switching circuits. ERICSSON TELEPHONES Ltd. 23 June, 1967 [12 Sept., 1966], No. 40731/66. Heading H3T. [Also in Division G1] A shaft rotation detector, capable of detecting the direction of rotation of a shaft when the shaft is rotating at a critical speed, comprises a disc D, Fig. 1, rotatable with the shaft and having three unequally spaced peripheral slots A, B, C (B being nearer to A than to C in the minor arc AC) and a sensing head capable of sensing the passage of a slot past a detection point. Each electrical signal produced by the sensing head (which may be magnetic or photo electric) when passed by a slot is applied to terminals P, Q, Fig. 2, and amplified by transistors VT1, VT2 to trigger a monostable device VT3/4. While its quasi-stable state lasts, each AND gate G1, G2 receives a "first" input; when it restores, the next monostable device VT5/6 is triggered. This applies a "second" input to the AND gate G1 for the duration of its quasi-stable state, which lasts twice as long as that of device VT3/4. At the critical speed signals sensed from slots A, B (irrespective of the direction of rotation of the shaft) cause simultaneous "first" and "second" inputs to open gate Gl. By triggering another monostable device VT7/8, this applies a "second" input to gate G2. If the shaft is rotating at the critical speed in the correct direction, device VT7/8 will remain in its quasi stable state long enough for the head to sense slot C so that the device VT3/4 applies a "first" input to gate G2 while it is still receiving the "second" input. Thus, if a motor has had time to accelerate the shaft from rest to the critical speed (measured by a timing circuit with a capacitor C12 charging in series with resistors RV1, R2) an inhibiting potential will have been removed from gate G2 via a diode D1 and the gate will open. A further circuit (VT15, 16, 17), may interrupt a holding circuit for the motor control relay MS after another interval of time unless an alternative holding circuit (through VT18), has been made. If the shaft is rotating in the right direction at the critical speed, the gate G2 delivers an output each time the slot C is sensed to charge a capacitor C13 and so switch transistors VT (12, 13, 14 and 18).
